Ⅰ. Product Overview
The PTG3000 Single Axis Gantry Stage from W-Robot is a premium long-stroke motion platform designed for large-format automation applications. Featuring a high-strength aluminum gantry beam, precision linear guides, and synchronous dual-drive technology, the PTG3000 ensures exceptional rigidity, smoothness, and motion accuracy even across extended travel distances.
This model is ideal for scenarios that demand high positioning repeatability and large working areas, such as semiconductor processing, PCB inspection, laser cutting, and component handling systems. The PTG3000 can also be integrated with Z-axis or rotary modules to form multi-axis motion platforms, offering maximum flexibility for custom automation solutions.
Ⅱ. Technical Features
Extended Stroke Capability – Standard travel up to 3000 mm or more for large-scale systems.
Dual Drive Synchronization – Uses dual belt or screw transmission to prevent torsion and enhance stability.
High Rigidity Structure – Machined aluminum beam for vibration resistance and mechanical precision.
Flexible Drive Options – Available with timing belt or ball screw drive for speed or load optimization.
Precision Linear Guideways – Deliver smooth and stable motion with low friction and long service life.
Universal Motor Mounting – Compatible with servo, stepper, or direct drive motors.
Integrated Cable Chain – Protects power and signal lines to ensure system reliability.
Repeatability – ±0.01 mm (depending on configuration).
Ⅲ. Application Fields
The PTG3000 gantry stage is well-suited for high-precision, long-distance positioning tasks, including:
Semiconductor equipment and PCB inspection machines
Laser engraving, marking, or cutting systems
Optical alignment and inspection lines
Precision dispensing and coating systems
Automated packaging and handling platforms
Material loading/unloading and transfer systems
Its rigid gantry architecture and configurable motion range make it an excellent foundation for building large-scale automation workstations.
Ⅳ. Model Selection & Customization
W-Robot provides complete customization and integration support for the PTG series:
Custom stroke lengths and payload designs
Choice of belt, screw, or dual synchronized drives
Servo, stepper, or linear motor compatibility
Mounting and flange interface customization
Optional cleanroom configuration or protective covers
Multi-axis integration (X-Y-Z or gantry systems)
CAD models (2D/3D) and performance data available on request
Ⅴ. Product Advantages
Exceptional stiffness and long-travel capability
Stable, smooth, and precise linear motion
Modular design for flexible automation layouts
Easy to integrate with robotic arms or inspection systems
Minimal maintenance with robust, durable components
Scalable for large-format, high-accuracy applications
Ⅵ. Installation & Maintenance
Verify installation surface flatness and rigidity before assembly.
Ensure synchronized drive tension is evenly adjusted.
Clean and lubricate guide rails periodically.
Check alignment and system accuracy every 6–12 months.
Avoid excessive vibration, dust, or extreme temperatures.
Secure motor coupling and mounting bolts to specified torque values.

FAQ

Listed below are answers to our most commonly asked questions. Don't see your question?Contact our customer service team. We would be glad to assist you.

What are the future development trends of linear modules and linear motors?

In the future, linear modules and linear motors will develop towards higher precision, higher speed, smaller size, intelligence, and integration with other advanced technologies (such as artificial intelligence and the Internet of Things).

What parameters need to be provided for customized linear motors?

It is necessary to provide detailed parameters such as load weight, stroke, speed, acceleration, accuracy requirements, installation method, and operating environment so that the manufacturer can design and manufacture a linear motor that meets the requirements.

How long is the customization cycle of linear modules?

The customization cycle depends on the complexity of the customization and the manufacturer's production capacity, generally about 1-4 weeks. The specific time can be determined by communicating with the manufacturer.

Can linear motors be upgraded?

The performance of linear motors can be improved by upgrading them with high-performance drives, optimizing control system parameters, and improving heat dissipation structures.

Is it easy to upgrade the linear module?

It is relatively easy to upgrade the motor, control system, guide rail and other components of the linear module according to actual needs to improve its performance and accuracy.

What is the after-sales maintenance service of linear motors?

Regular manufacturers usually provide comprehensive after-sales maintenance services, including fault diagnosis, maintenance guidance, parts replacement, etc., but the response speed and quality of after-sales maintenance services may vary from manufacturer to manufacturer.

What is the warranty period for linear modules?

The warranty period of linear modules from different manufacturers varies, generally around 1-2 years. The specific warranty period can be confirmed with the manufacturer at the time of purchase.

What should we pay attention to when integrating linear motors with other equipment?

Attention should be paid to issues such as interface compatibility, signal matching, control logic coordination, and installation space and layout between devices to ensure that the devices can work together.

Can the linear module be integrated with other equipment?

Absolutely. Linear modules can be integrated with other devices such as robots, sensors, and vision systems to build more complex and intelligent automated production lines.

What kind of control system do linear motors require?

Linear motors typically require a high-performance motion control system that can achieve precise position control, speed control, and thrust control, such as a dedicated linear motor drive with a motion control card or a high-end PLC.
